MMG Checkout for WooCommerce in Guyana: The Revamped GY Plugin That Works With Block Checkout

The Most Advanced MMG Payments Plugin.

This plugin adds MMG as a payment option at checkout and it works with both WooCommerce Classic Checkout and WooCommerce Block Checkout. Customers are redirected to MMG’s secure hosted payment page, they complete payment, then they return to your store. Once they return, the order updates automatically in WooCommerce so your order history, invoices and customer account pages stay accurate.

Latest Version: 2.14.13

Read Changelog

2.14.13

Fixed Live (Production) checkout URL to use the correct MMG payment host (mmgpg.mymmg.gy).
Added an automatic migration that replaces the old mmgpg.mmg.gy URL in saved settings to prevent “This site can’t be reached” errors after switching to Live.

2.14.12

Added the MMG logo icon next to the MMG Checkout payment method label, aligned neatly like other gateways.
Ensured compatibility with both Classic checkout and WooCommerce Blocks checkout.

2.14.11

Fixed QR checkout link mode so QR links open a real WooCommerce order‑pay page that shows payment options and the Pay button.
In checkout‑link mode, QR orders created by admins are stored as guest orders so customers can pay without being forced to log in.
In checkout‑link mode, the plugin no longer forces MMG as the order payment method, allowing the pay screen to load other gateways normally.

2.14.10

Changed QR checkout link mode so newly generated QR links become standard WooCommerce /checkout/order-pay/... links (no custom mmgwc_qr query token).
In checkout‑link mode, the plugin creates the order at QR generation time (similar to Payment Requests), then customers land on checkout first and choose a payment method.

2.14.9

Added a QR Payments alternative redirect mode that sends customers to the WooCommerce pay screen first (useful when direct MMG redirects are blocked by security plugins, caching, or hosting rules).
Added a checkbox setting under MMG Checkout → QR Payments to enable the alternative checkout flow.

2.14.8

Fixed QR public token handling so tokens are safely normalised even on hardened setups where query parameters may arrive in unexpected formats.
Improved fail‑fast behaviour for invalid links and added no‑cache headers for QR token requests.

2.14.6

Fixed an admin UI glitch where a stray “QR Payments” link could appear in the top‑left during page loads (especially on mobile).
Cleaned up admin menu rendering to prevent unintended output during menu registration.

2.14.5

Fixed QR payments redirect behaviour so QR links now send customers straight to the MMG payment page reliably.
Adjusted redirect handling to avoid WordPress safe‑redirect restrictions that could push users back to the site homepage.

2.14.4

Improved QR link compatibility by defaulting to a query‑string QR link format for better reliability across security plugins and hosting rules.
Reduced edge cases where pretty links could trigger forced‑login redirects.

2.14.3

Fixed a fatal TypeError in the QR payment handler caused by passing the wrong variable type into the order‑creation function.
Hardened token parsing to prevent invalid data from reaching the QR order builder.

2.14.2

Improved public handler detection to accept multiple QR URL formats cleanly.
Enhanced rewrite and handler checks for more resilient QR links.

2.12.3

Removed the global footer injection and kept support branding only where intended.

2.12.2

Corrected the setup flow in Overview and Help: request UAT package → import → test → send test video to MMG → receive Live package → import → switch to Live.
Updated plugin row links (View Details and Visit Plugin Site) to the new plugin landing page.

2.12.1

Fixed My Account endpoint handling that could cause critical errors on customer account pages.
Updated Help and Overview to match the latest feature set and navigation.

Locked core management pages (Feature Manager, Role Manager) so they cannot be accidentally disabled.

Fixed analytics menu registration so the Analytics page reliably appears under MMG Checkout.

2.11.0

Customers can view invoices and subscriptions inside their My Account area. They can pay, renew, and check status without contacting support.

Send renewal reminders with a pay link for subscription products you define. Tracks last paid, next due, and overdue status automatically.

Subscriber Controls and Overdue Tags

Add grace periods, overdue tagging, pause or resume reminders, and stop after missed cycles. Gives you real control over renewals and follow ups.

Per-Subscriber Price Locking

Lock the renewal amount for a specific subscriber when needed. Keeps pricing consistent for agreements or special customers.
